STOOL OR SEAT STANDARD.

$PECIFICATION forming part of Letters Patent No. 300,116, dated June 10,1884:.

Applicaiitn filvd January 23, 1884. (X model.)

To all whom it may concern]:

Be it known that I, HENRY OcoRR, of Milwaukee, in the county ofMilwaukee, and in the State of \Visconsin, have invented certain new anduseful Improvements in Stool or Seat Standards; and I do hereby declarethat the following is a full, clear, and exact description thereof. l Myinvention relates to standards of stools." seats, and other articles offurniture; and it consists in certain peculiarities of construe tion, as.will be more fully set forth hereinaf ter.

In the drawings, Figure l is a side elevation of a stool embodying myimprovement,

- partly broken away to better show the con spective view of thesecuring-ring inverted.

My improved standard consists, primarily, of three parts: A, the hollowbody; B B B, the legs, and O the stem.- The body A has vertical wallsfrom its base to about one'third of its height, where its diameter issomewhat increased to form the outer square shoulder, a, and from thispoint the body tapers gradually upward, terminating in a preferablyornamentally-molded top, a, with a central opening, a", to receive theseat-stem G, which is kept steady by means of inwardly-projecting pointsor lugs a on the top a. The legs B B B are secured to place in thefollowing manner: Each of these legs (which are preferably three innumber) terminates at the upper end in vertical edges 1), (of whichthere will be two to each leg when the legs are cast semicircular insection, as shown,) which conform to the rounded surface of the lowerpart of the body A, and the three leg edges b b, &c., completely'encompass it, and have downward projections I) b. The base of the hollowbody A is either wholly closed or partly so by plate or bar A, and thishas a central vertical screwthreaded hole formed therein.

D is an annular molding, which is pushed up from below around the lowerpart of the body A, and then the three legs are pushed up to place, andto secure a tight fit lugs 12 are formed either on the outer uppersurface of the top of each leg, as shown in the drawthe stem C when inposition.

the threaded hole in the bottom plate or bar,

A, thus firmly fastening all these parts to gether in proper position.

On the interior of the hollow body A, aild about midway of the height ofthe tapering portion, are cast the three lugs (4* a a which serve asguides to steady the lower part, 0 of This stem has primarily threeparts, of which the upperpart is made hollow and flaring, as at c, toreceive the shank of the seat G. The intermediate portion, 0. is a solidround body with vertical faces-that is, everywhere of equal diameterwhilc the lower part, C is of less diameter, and is provided with avertical exterior groove, 0, furnished with the ratchetteeth 0 0 whichextend only about midway from the back or bottom of the groove to thecircumferential line of the part 0 while the lower tooth, 0, extends outbeyond, as shown, to form a stop for the paw1-block, as hereinafterdescribed, and below and opposite to this tooth 0 there is formed a lipor projection, 0*, which serves as a stop to prevent the stem from beingaccidentally drawn up out of the hollow body A in raising the seat, asit would come in contact with one of the described lugs a and yet inputting the stem into the body A these lugs form no hinderance, as thestem can then be turned so that the projections c and 0" will passbetween the lugs at i In the upper part of the body A there is formedthe slot or opening (i and the body A is strengthened or re-enforced atthe base of the said slot, as shown at a, and this slot is to receivethe pawl block H, by means of which the height of the stem, andconsequently of the seat, is to be regulated. The general shape of thisblock is shown in section in Fig. 2, and itslower end terminates in thepawl h, which engages with the ratchet-teeth c", as shown. The front ofthis block has a straight surface at h, below which it is cut away orcurved in,- ward at h to form the shank of the pawl, and

its bearing-surface or pivotal point is shown at h on the rear of theblock proper, above which it is rounded out or cut away, so as to enableit to be operated with a rocking motion on said bearing or fulcrum-pointm, as hereinafter set forth, and this rounded portion terminates in anoutward-extending hook or latch, h, for use in freeing the pawl fromengagement with the ratchet-teeth. When the pawLblock has been placed inposition bear- 1ng against the stem in the hollow body, and also at hupon the body A at the base of the slot a it is secured in place againstthe liability of falling out by means of the annular securing-ring ormolding I, which is slipped down over the standard from above. This ring(shown inverted in perspective at Fig. 5) is provided with threeinterior webs or flanges, it i, that project from the interior surfaceof the molding toward a common center, and which webs are made to taperso as to fit firmly down upon the tapered exterior surface of the body Aand clasp it firmly from all sides, while the space between two adjacentwebs, v; i, is sufficient to enable the pawlblock H to work freely, andthese webst' have another function, as described further on.

The operation of my device is very simple, yet extremely effective.\Vhen the parts have all been put together, as shown in Figs. 1 and 2,and it is desired to elevate the stem and seat, it is only necessary topull up on the latter, when the stem will be raised and the pawl h ofthe block H will slip automatically into the notch below, and thus on,engaging in turn with the several teeth until the stool is at theelevation desired, the stop 0 limiting the downward motion of thepawl-block, as well as the upward motion of the stem 0. Now, if it isdesired to keep the seat at such elevation secure against accidentallowering, it is only necessary to turn the securing-ring or molding Ipartly around until one of its webs or flanges bears directly againstthe straight surface h of the front of the pawlblock H, and all theparts will be firmly looked, as shown in Fig. 3, no matter how much thestool may be shaken or moved. If it is desired to release and lower thestem, first the securing-ring I must be turned around, so that its web03 will no longer press against the front of the pawl-block H, and thenby lifting on the latch h the block can be moved and rocked on itsfulcrum-point h and its rounded upper rear edge brought against thesurface 0 of the stem, which will force the pawl h free from engagementwith the ratchet-teeth c and enable the stem to drop, by its own weight,the desired distance, and then, by releasing the latch h, the pawl-blockwill automatically act by its own weight, and the pawl h will instantlymove into the notch opposite it. By reason of the teeth only extendingpart of the depth of the groove 0, the said groove always presentsstraight side walls, which retain the pawl h when free from the teeth,and prevent any lateral displacement, and hence it is impossible for thelatch-block to get out of place.

The advantages of my improved standard are manifold, and though I haveshown it with especial reference to stools and seats, it is obvious thatit may be employed with tables, stands, or any other articles offurniture having standards or legs which it is desirable to vary inheight. It is simple in construction, but very sure in its operation,and has the great advantage of being what is known as a knockdownstandardthat is, one which is in several pieces, readily separable, soas to occupy but little space i-ntransportation or storageand it iscomposed wholly of castings or separate pieces of metal, so that if onepart becomes broken it can be readily restored without requiring thewhole device to be cast or otherwise formed anew.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, in a standard for furniture, of the hollow body andits supportinglegs with a sliding stem having ratchet-teeth, asdescribed, a pawl-block, H, and webbed ring I, as set forth.

2. In a standard for furniture, the combination of a tapering body andits support with a sliding stem having ratchet-teeth, as described, apawl-block, H, and a securingring having webs i, as and for the purposeset forth.

3. The combination, with body A, having slot a its support, and stem 0,having groove and ratchet-teeth formed therein, of a pawlblock, H,substantially as described, and a ring for locking the block.

4. The combination of the hollow body A and a suitable support therefor,having slot 0?, stem 0, provided with groove and ratchetteeth formedtherein, pawl-block H, with pawl h, and securing-ring I, having interiorwebs or flanges, i, substantially as set forth.

5. In a standard for furniture, the combina tion, with the hollow body Aand a suitable support therefor, having slot a, of thevertically-movable stem 0, with solid vertical portion 0 and lowerportion, 0 the latter having an exterior groove, 0, with straight walls,and ratchet-teeth 0 formed therein, and a securing-ring and pawl-blocksuspended loosely against the stem.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
